KAIST develops coating tech that controls droplet formation and removal, boosting heat transfer 5.5x

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have engineered a novel coating technology capable of simultaneously managing the creation and elimination of water droplets. This breakthrough significantly boosts heat transfer performance, achieving an efficiency increase of up to 5.5 times.

The research, led by Professor Nam Young-seok from the Department of Mechanical Engineering and Professor Im Sung-gap from the Department of Chemical and Biomolecular Engineering, focuses on optimizing droplet behavior by precisely controlling the thickness and structure of an ultrathin polymer coating. This dual control mechanism is key to enhancing the overall heat exchange process.

This advanced coating technology is expected to find practical applications across various industries. Potential uses include improving the efficiency of power generation facilities, enhancing the performance of desalination plants, and providing advanced cooling solutions for electronic devices. The development marks a significant step forward in thermal management solutions.
